December is a period of intensive network usage – from planning holiday shopping and searching for gifts to sending seasonal greetings and catching up on favorite streaming services during winter evenings. During this peak period, connection stability and speed become crucial. We examined how Polish mobile operators handled the December network load by analyzing thousands of tests conducted by RFBENCHMARK app users across 5G and 4G LTE technologies.

Mobile Internet in Poland – What Was the Situation in November 2025?

In November 2025, T-Mobile remained the leader in 5G technology regarding download and upload speeds, maintaining a clear advantage over the competition. Orange steadily held the second position, while Play and Plus competed for the remaining spots with significantly lower transfer results. In the latency (PING) category, Orange maintained its leadership status, offering the lowest values, which translated to the highest network responsiveness for gamers and real-time application users.

In the 4G LTE segment, November saw T-Mobile’s dominance in download speeds, though the differences between operators were much smaller than in the case of 5G. Play demonstrated high efficiency in the data upload category, slightly ahead of T-Mobile. Similar to the newer technology, Orange remained unrivaled in terms of the lowest ping, while Plus recorded the highest response times, a trend that has persisted for many months.

How Did We Collect the Data for the Ranking?

Measurements are collected from users using our mobile application. Thanks to it, we can measure the basic parameters of the mobile network – including signal strength and quality depending on the technology used by the mobile device, information about the mobile network operator, and the country where the smartphone is located. Additionally, on demand, Internet speed measurements during download and upload are performed, as well as a latency test.

When the application detects a poor-quality voice connection, lack of mobile Internet services, or another issue, it has the ability to report the user’s current location where the problem occurred.
